Flickr-Lube is a simple ruby script designed to make it easier to FuckFlickr. If you already have a bunch of photos up on flickr, this will pull down those photos, put them in the appropriate sets, and make sure they have the right descriptions and titles.
Flickr-Lube is ruby, so you need to have ruby installed for whatever platform you are on. In addition, it uses ruby gems and the fleakr gem.
If you already have ruby and rubygems installed, you can just gem install fleakr or sudo gem install fleakr.
Edit this script to put in your flickr username and you should be ready to run it.
